Article Home Adult and Senior Health Dysentery


Acute watery diarrhea is an extremely common problem, called Gastroenteritis, which can be fatal due to severe dehydration. This applies to both adults and children, especially in the very young and the old or in those who have poor immunity such as individuals with HIV infection or patients who are using certain medications that suppress the immune system.


Dysentery is typically the result of unsanitary water containing micro-organisms which damage the intestinal lining.

There are two major types of dysentery due to micro-organisms: amoebic dysentery, and bacillary dysentery.


Signs & symptoms

  • Initial management of dysentery is to maintain fluid intake using oral rehydration therapy
  • If this cannot be adequately maintained, either through nausea and vomiting or the profuseness of the diarrhea, then hospital admission may be required for intravenous fluid replacement
  • Ideally no antimicrobial therapy is started until microbiological microscopy and culture studies have established the specific infection involved
